MENUS
The menu items, for the most part, are identical in both the Register and Basic template
views. The few exceptions will be indicated in the descriptions below. Only two menu
items will be discussed in this section, as the others are self-explanatory.
4.5.1
In the Basic template, this menu contains the message types to be transmitted.
Selecting message types opens a window that the user can configure to transmit a
message. Example, selecting Messages > Universal > Universal opens a window for
transmitting a normal (up to eight bytes) message.
The CAN Kingdom message-type menu items are for transmitting messages that
adhere to the CAN Kingdom higher-layer protocol (HLP).
4.5.2
The options menu contains the configurable properties of both the hardware and the
software.
The default numeric base is selected by Options > Global. Auto-save switches are also
contained here.
Options > MCP2515… is where the LPT port address is selected. It is also where the
oscillator frequency is set in software. Additionally, this menu contains a switch that
determines whether or not the MCP2515 will be reset on file open. This feature is for
those users who want to switch between templates without changing the MCP2515
configuration (e.g., masks and filters are set to receive ALL messages in the Basic
template, unless this box is deselected).

The oscillator frequency must be set in software to match the hardware
so the software can configure the bit timing registers correctly. The
formulas for bit timing contain an oscillator frequency.
